Yup, just put it in the back of the fridge for about 3 weeks. I keep the temp at about 38F degrees; too cold would kill the "yeast beasties". It's always been consumed before it went bad. If you "decant" it (pour it into another bottle & rinse out the sludge at the bottom) it'll keep a little longer.

Next year I may get a glass jug with a top that lets the gas escape (when the plastic jug expands, you have to let the air out occassionally). Maybe even a hydrometer to check the alcohol percentage.
